For Southern California property owners, reducing water use often starts with the fixtures used every day. An aging toilet, inefficient showerhead or high-flow faucet can waste water long before anyone notices a problem. Replacing those fixtures with well-chosen alternatives can help lower consumption without making bathrooms or kitchens less practical.
The best upgrade depends on the building. A homeowner may see the greatest benefit from a bathroom retrofit, while a restaurant, hotel or office may need to focus on fixtures that serve dozens of people each day.
WaterSense Toilets That Use Less Water
Toilets are a major source of indoor water use. EPA WaterSense-labeled tank toilets use 1.28 gallons per flush or less and must meet performance requirements, making them a practical replacement for many older models. For households and businesses planning a renovation, compare both flush volume and the fixture’s suitability for the space.
Some Southern California customers may qualify for incentives on premium high-efficiency toilets using 1.1 gallons per flush or less. Review the SoCal Water$mart toilet rebate details before purchasing; eligibility, funding and local rules can change.
Low-Flow Showerheads Without the Weak Spray
Older showerheads can send more water down the drain than necessary. WaterSense-labeled models use no more than 2.0 gallons per minute and are independently evaluated for spray force and coverage. That makes them worth considering in homes, apartments, hotels, gyms and other properties with frequent shower use.
The EPA WaterSense showerhead guide explains the efficiency and performance standards behind the label.
Efficient Bathroom Faucets and Aerators
Replacing an entire faucet is not always necessary. In many bathrooms, a compatible water-saving aerator is a straightforward way to reduce flow. WaterSense-labeled bathroom faucets and accessories are designed to save water while remaining useful for handwashing and everyday tasks.
For commercial restrooms, automatic shutoff or sensor-operated fixtures may also reduce unnecessary running time. Select products based on traffic, accessibility, maintenance needs and applicable local fixture standards—not water savings claims alone.
One important distinction: EPA WaterSense labeling applies to qualifying private bathroom and bar-sink faucets, not every kitchen or public restroom faucet. See the EPA bathroom faucet guidance for details.
Commercial Flow-Control Valves
Businesses with multiple sinks and showers may benefit from flow-control devices installed at appropriate fixtures. These devices can reduce flow while maintaining useful pressure, but compatibility matters: a device that works well at a restroom faucet may not be appropriate for equipment that requires a specific flow rate.
SoCal Water$mart lists eligible plumbing flow-control valves and notes potential reductions of up to 60% for qualifying applications. Check its current program requirements before ordering or installing devices.
High-Efficiency Urinals for Busy Properties
Offices, restaurants, schools and other commercial properties can save water by replacing older urinals with ultra-low-flow or waterless models where appropriate. Maintenance practices, plumbing compatibility and user volume should all factor into the decision. A qualified plumbing professional can help evaluate whether a particular model makes sense for the building.
The SoCal Water$mart commercial rebate program lists eligible categories, including qualifying urinals, toilets and flow-control devices.
Choose Fixtures That Fit Your Property
Start by checking which fixtures are used most often and whether leaks or mineral buildup are already affecting performance. Compare product specifications, confirm local plumbing requirements and check rebate eligibility before making a purchase. In commercial spaces, pay particular attention to accessibility and the needs of connected equipment.
Water-efficient fixtures work best alongside routine leak checks and maintenance. A small, persistent leak can undermine the savings from even a well-designed upgrade.
